Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| describe_tableA | 查看表/视图的完整结构：列清单（类型/可空/默认值/注释）、主键与约束、全部索引及其定义；视图返回视图定义 SQL，分区表返回分区清单。 |
| execute_selectA | 执行只读 SELECT 查询（唯一允许的 SQL 入口）。仅接受单条 SELECT/WITH 语句：禁止 DML/DDL、SELECT INTO、行锁、多语句与危险函数；查询在服务端强制的只读事务中执行。 |
| list_schemasA | 列出 GaussDB 数据库中的 schema（模式）清单，含每个模式下的对象数量与注释。默认排除系统模式。 |
| list_tablesA | 列出 GaussDB 数据库中的表和视图清单（表名、类型、估算行数、注释）。可通过 schema 参数过滤到指定模式。 |
| test_connectionA | 测试 GaussDB 数据源连通性，返回服务器版本、当前数据库、用户、只读状态与连接耗时。不指定 instance 时测试默认实例。 |

Scored across 5 tools
Each tool targets a distinct resource or action: listing schemas, listing tables, describing a specific table, executing read-only queries, and testing connectivity. There is no overlap or ambiguity between them.
All tool names follow a consistent verb_noun pattern in snake_case (describe_table, execute_select, list_schemas, list_tables, test_connection). The naming is uniform and predictable.
With 5 tools, the set is well-scoped for a read-only database exploration server. Each tool earns its place and the count is appropriate for the server's purpose.
The tool surface covers the full read-only workflow: discover schemas, list tables/views, inspect table structure, execute queries, and verify connectivity. No obvious gaps exist for the stated read-only domain.
